Assessment of Attack Frequency in PFAPA Patients Based on Therapeutic Modalities.

Aim: This study aims to present the clinical characteristics of patients with PFAPA syndrome, and to compare the effects of corticosteroid usage, colchicine prophylaxis, and tonsillectomy on the frequency of attacks in patients with PFAPA syndrome.

Methods: Patients aged between 6 months and 18 years presenting to our Paediatric Rheumatology clinic between 2017 and 2021 who were diagnosed with PFAPA syndrome and followed up for a minimum of 12 months were included in this study. The demographic and clinical characteristics of the patients, laboratory findings, attack durations, and treatments were recorded.

Intussusception as a rare manifestation of immunoglobulin A vasculitis: Risk factors and treatment.

Aim: To identify the risk factors associated with intussusception in children with immunoglobulin A vasculitis (IgAV)-gastrointestinal (GI) tract involvement and to evaluate the outcomes of medical treatment and surgical intervention and the course of patients with intussusception.

Methods: This retrospective study was conducted in 157 patients under 18 years of age who were followed up with the diagnosis of IgAV-GI tract involvement between January 2015 and September 2022. The characteristics of the patients who developed intussusception were evaluated in detail.

Evaluation of Suspected COVID-19 Patients in a Pediatric Emergency Department.

Coronavirus disease 2019 (COVID-19) is now a global pandemic. The aim of this study was to investigate the prevalence of COVID-19 in pediatric patients and to compare the characteristics of positive and negative patients. This study conducted from March to May 2020 in a tertiary children's hospital.

A comprehensive study of myocardial redox homeostasis in naturally and mimetically aged rats.

Age-related myocardial dysfunction has important implications with impaired redox homeostasis. Current study focused on investigation of redox homeostasis and histopathological changes in the myocardium of mimetically (MA), naturally aged (NA), and young control (YC) rats. Chronic D-galactose administration to young male Wistar rats (5 months old) was used to set up experimental aging models.

Age-related changes in rat prostate tissue; perspective of protein oxidation.

Background: Increased systemic oxidative stress is considered as an important risk factor for prostate cancer occurrence; however, the relationship between impaired redox homeostasis of prostate tissue and aging remains unclear.

Objective: In our study, we hypothesized that age-related deterioration of redox homeostasis in prostate tissue may be considered as a predisposing factor for prostate cancer occurrence.

Methods: Sprague-Dawley rats were divided into two groups as young control (5 months) and naturally aged (24 months).

Oxidation scrutiny in persuaded aging and chronological aging at systemic redox homeostasis level.

Background: The effect of the natural aging process on systemic redox homeostasis is previously documented. However, none of the studies specify the effect of experimental aging on systemic redox homeostasis. The purpose of this study is to clarify the ambiguity raised in preliminary reports as to mimetic aging dependency of the type and magnitude of oxidative damage on constituents of plasma.
